6805 Compendium

The 6805 family is Freescale's simplest and least-expensive family of microcontrollers. The breadth of devices is quite large, ranging from tiny 16-pin chips to larger parts with more memory and peripherals. Nearly all the devices are single-chippers and use ROM or OTP ROM. Though intended to be replaced by the newer HC08 family, the '05 devices are still widely used, widely available, and excellent choices for all sorts of simple tasks.
